Increased democratization leads to a more ineffective government, constitutionalism exists to remedy this problem and that is the reason why the rule of the majority will be restricted. The majority do not care about "petty details" like torture restrictions, as they can not relate to them in everyday life. Let's stop pretending that voters do not have a stake in this game, and rather face the reality that voters are quite fine as long as the promises are short-term gains.
This is the problem with politics, and as long as we keep believing that the public and the majority is right, we will keep seeing these things, and lobbyist groups will keep dominating.
See Zakaria, Tockqueville and other writers about democracy versus freedom and human rights for this.
And in terms of DRM, this is really the problem, it's a niche discussion with a major outreach, every single Windows user out there will at some point feel DRM restrictions, but seeing as they do not understand the problem they accept the status quo. If they did understand, Linux or at least another proprietary to Windows would have been the paradigm long ago.
There is never time to do it right, but always time to do it over.
